Yes, the HUE bundle can be confusing. Four game versions are included:
1) HCE
2) Harpoon3 v3.6.3
3) Harpoon3 ANW v3.9.4
4) Harpoon3 HUE v3.10.0
Since you have previously played HCE and H3, you do not need to review their differences.
Harpoon Classic and Harpoon3 Comparison
https://www.youtube.com/watch?v=LpXyEd6MxgUThe three different versions of H3 are:
v3.6.3 was released in 2001, is only solitaire, and has (IMO) the most aggressive AI
v3.9.4 was released 2006, has MP capability, fixed some v3.6.3 bugs, but added many, many more
v3.10.0 was released in 2010, is only solitaire, fixed virtually no bugs, and only added more problems
You can select the version you like best. There is a different version of the PlayersDB customized for each of the game versions.
